<When an error is detected by diagnosis>
Detailed information is displayed under the judgment result. In detailed information, the name
of the test where an error was detected is indicated.
<How to view the error result>
The following screen is an enlarged view of the detailed information indicated above.
Explanation of the detailed error information is described.
[no] means that optional PCBs are not mounted.
When [no] is displayed although an optional PCB is mounted, it means that an error has been
occurring.
[NG] means that an error occurred to PCBs mounted as standard.
NOTE:
Once the tool is activated, this machine reboots after approx. 2 minutes.
After completion of the diagnosis, be sure to turn OFF and then ON the main power.
By turning the power OFF, the operation of this tool completes.
